Unloading the Adapter Driver

To replace an existing inbox driver with a new out-of-box iSCSI driver, unload the

existing driver and load the new driver. To unload the driver, stop all applications

using the driver and then unload the driver.

1. If the iqlremote agent is running, stop the agent by issuing the following

command:

# service iqlremote stop

2. To unload the driver using modprobe, issue the following command:

# modprobe -r qla4xxx

Rebuilding the RAM Disk

To automatically load the driver by rebuilding the RAM disk to include the driver,

follow these steps:

To create a backup copy of the RAM disk image, issue the following command:

 For RHEL 6.5:

# cd /boot

# cp initramfs-[kernel version].img initramfs-[kernel

version].img.bak

 For SLES 11 SP3:

# cd /boot

# cp initrd-[kernel version].img initrd-[kernel

version].img.bak

2. Rebuild the initrd image with driver by issuing the following command:

 For RHEL 6.5:

# mkinitrd -f /boot/initramfs-[kernel version].img 'uname

-r'

 For SLES 11 SP3:

# mkinitrd

3. Reboot the host to boot from the new initrd image with new driver.

NOTE

Depending on the server hardware, the RAMDISK file name might be

different.
